YMMV, but my experiences with SBCL were way better than with Go. Using Hunchentoot and the other Quicklisp libraries made developing fun again. With Go I had to constantly worry about errors, repeat the same code snippets over and over again, had to comment out "unused" variables just to try something... not fun. That said, let's see how Lisp works out once I cross the 10'000 LOC barrier. But by then it won't be a microservice anymore, anyway...
